520. RDataMining - a package for data mining- A comprehensive R Package for Data Mining, with contributions from many R users.
If you have developed or will implement any data mining algorithms in R, please participate in this project to make your work available to R users worldwide.

525. Marketing Analytics Repository- The Marketing Analysis Repository is a project that aims to bring quantitative Marketing and R together. For example, by developing an R package that supports typical analysis and decision tasks.

526. Phylobase Extension- This package provides classes and methods which help read/write/manipulate branch-annotated phylogenetic trees (SIMMAP-format) and supports for a few other extra phylogenetic tree features (like tree weight).

530. WZD - blog package- This package goes along with the blog wagezudenken.blogspot.com, which will feature datasets from various topics, data visualizations including cartography, statistical methods and tools. The first R function implemented is a Sweave driver for bloggers.

531. CHAID- This package offers an implementation of CHAID, a type of decision tree technique for a nominal scaled dependent variable. The method detects interactions between categorized variables of a data set, one of which is the dependent variable.

532. Testing HWE for Multiallelic Genes- This package calculates plain and fully conditional P-values for the root-mean-square statistic, chi-square statistic, and log likelihood-ratio statistic for the user-provided genotype counts to be consistent with the Hardy-Weinberg equilibrium model.

536. DirichletReg - Dirichlet Regression- This project implements Dirichlet regression models for the analysis of compositional data. Starting with the basic fit routines, new functions (model selection, graphics, etc.) will be added and tested here, before being submitted to CRAN.

537. Rcpp - Seamless R and C++ Integration- The Rcpp package provides a C++ library which facilitates the integration of R and C++. R data types (SEXP) are matched to C++ objects in a class hierarchy. All R types are supported and each type is mapped to a dedicated class.

538. MODISTools- MODISTools uses the MODIS SOAP Web Service provided by ORNL DAAC for remote retrieval and processing of large subsets of data -- as a batch process -- from NASAs online archive of remotely-sensed data from the MODIS satellites.
